tyvek - an unpredictable material

I have followed a 3day workshop, all about working with textiles.  Working with Tyvek, a synthetic lightweight and durable material was new to me.  It is waterresistant and durable, you can colour it with paint and when heated it makes funny patterns.  I made some pretty stuff, and I enjoyed myself very much !

Tyvek is a funny thing.  the result is unpredictable

I 'm thinking of rings....
